ABSTRACT
Leiomyoma is a benign tumor arising from smooth muscle cells. They are commonly found in the uterus, skin, and gastrointestinal tract. However, it is rare in the head and neck area. Especially, only 3% of leiomyomas in the head and neck area occur in the nasal cavity. Rhinologists need to know leiomyoma as a differential diagnosis of the tumors in the nasal cavity. Herein we present two cases of angioleiomyoma in the nasal cavity and review the literature.

Renal cell carcinoma (RCC) is the most common malignant tumor of the kidney which takes up 85% of primary malignant renal tumors. RCC commonly metastasize to the lung, regional lymph nodes, bone, liver, and head and neck sites in decreasing order. Although RCC is the third most common infraclavicular neoplasm (after lung cancer and breast cancer) which metastasizes to the head and neck, it is a rare situation that RCC metastasize to the paranasal sinuses. In this paper, we report a case of metastatic RCC involving the sphenoid sinus after radical nephrectomy with a review of literature.

BACKGROUND AND OBJECTIVES: Individuals with similar degrees of hearing impairment frequently show significantly different speech understanding in noise stimulation. A Korean version of the Hearing in Noise Test (KHINT) has been developed to assess the ability to recognize speech in noise. However, sentences in KHINT have been designed for subjects older than 16 years old and there have been no reports on KHINT related to the effect of age in the children younger than that age. The objective of this study was to evaluate the result of KHINT in children. SUBJECTS AND METHOD: One hundred one children between 7 and 16 years with no otologic history and normal hearing were included in this study. KHINT was conducted under the following four different conditions: speech in the quiet environment, with noise in the front, with noise in the right or in the left. The mean reception threshold for speech (RTS) in the quiet condition and signal to noise ratio (SNR) in the noisy condition were measured under four different conditions. RESULTS: There was no correlation between age and RTS. However, SNR with noise in the front, left and right conditions, as well as composite SNR, showed significant decrease with the decreasing age of children. CONCLUSION: According to KHINT, children showed decreased speech with decreasing age. Therefore, a separate KHINT with correlation factors to assess children's functional hearing ability in noise should be developed.
